This invention relates to window shade rollers of the spring operated type.

The object of the invention is to provide superior and economical means of mooring or 5 anchoring the spring of a Window shade roller to a supporting member, such as a spindle.

Other objects and certain advantages of the invention will be more fully set forth in l the description of the accompanying drawings, forming a part of this speciiication, in

which: l

Figure l is a view showing the shade roll mounted for use on a window frame. 15 Figure 2 is a sectional view taken on line 2-2, Figure 1, detailing the manner of anchoring the spring to the spindle of the shade roll.

Figure 3 is a detail sectional view taken on line 8-3, Figure 2, further illustrating the manner in which the end of the coil spring is secured to the Wooden spindle.

Figure 4 is a View of the ferrule or bearing cap at the end of the spindle.

Figure 5 is an end View showing the ratchet and pawl mechanism `for controlling the movement of the shade reel on the spindle.

As disclosed, the window frame 1 is provided at the top with brackets 2 and 3. These brackets hold the window shade roller 4, the roller being mounted in the bracket 2 on the right hand side by a pivot 5, and on the left hand side by a flat shank member 6 non-rotatably secured in the bracket 3. To the middle of the window shade roller is attached the window shade cloth 7 The reel 8 of the window shade roller is hollow and has mounted therein a spindle 9. The spindle is secured rotably at its inner end in a socket 10 nonrotatably secured in the reel by a pin 11. The other end of the spindle is non-rotatably secured by the flat member 6 which is embedded in the spindle. The mechanism designated at l2, at the outer end of the spindle for regulating the rolling and unrolling olr the shade, is the conventional mechanism in common use and described in United States Letters Patent No. 44,624. This mechanism and its supporting plate 13 hold the WALLACE E. SARRAN, or CINCINNATI, oHIogAssrGNRro LCHAs. W.

spindle within the reel, infturn i,

the reel end by meansoffacap14.l On the end `of the spindle next to 'the mechanism 11'4v is a metal ferrule `or Ibearing cap` 15,n0nro-A tatably secured to the spindle. This fer-rule serves as one bearing for the reel. About the; L

spindle is acoilfspring 16 secured at the inner end to the socket member as.` disclosed, 'by

passing therethrough. At the otherend this springis securedt'to the spindleby passing through two clips 17 .projecting from the fer-` :i rule ,15. kThis much of the structure isconi ventional.

The weakest point inthe structure, y

point which gives the vmost trouble to the inw stallers and users of window shades, isythe f mooring between the ycoil spring and the spindle. Normally the'clips are bent downupon' the spring as tightly as possible to hold it. Often these clips yield and permit the spring to slip, thereby renderingthe window shade unusable. This mooring has also been accomplished by running the end of the spring completely through the spindle but it is difficult to assemble the spring and mandrel in this relationship without injuring either one or the other. It is also expensive. The present invention solves the problem by providing the end of the spring with a small inwardly turned terminal hook 18 which can be pressed into the wood of the spindle by hand, orcan be left contacting the Wood of the spindle ready to dig into it if slippage occurs. The manufacturing of springs terminating in hooks presents no diiiiculty since springs are conventionally made by being coiled upon a mandrel with one end extending therethrough, and can be cut to provide the hook tional roller, that is, the point of mooring between the spring and its support. Having described my invention, I claim 1. In a window shade roller construction of the class described, including a wooden spindle, a roller, mounted thereon, and a coil spring surrounding said spindle secured at one end to the spindle and at the opposite end to the roller; an additional attachment between said spring and said spindle, comprising, an inwardly turned end on the end of the spring attached to the spindle, said inwardly turned end providing a fang in contact wit the wood of the spindle and clinching thereintoin case of slippage of the other means attaching the spring tothe spindle.

" 2. In a window shade roller construction of the class described, including, a' wooden spindle, a roller mounted thereon, a coil spring sevcured at its respective ends to the roller and the spindle, and clips secured to said spindle frictionally securing the end: coil of' said spring; an additional attachment between the spring and spindle, comprising, a hook formed on the end of the spring by inwardly turning the end of said spring, said hook sinking into the wood of the spindle and clinching thereinto in case of slippage of said frictional clip'attachment. f

In witness whereof I hereuntoy subscribey my name. WALLACE E. SARRAN.
